No, you will have to do the things I wrote in my first reply:
In INFORMATION table 255, set the INTERCEPT MBOX to
a non exsting extension number.
Procedure:
Log-on to you Octel /VMX 200.
Go to update, press U for Update.
.L SLOT, to see the COS for your PORTS for your VMX 200.
.L PROF with the COS value for above.
The INFO table for the PORTs has an INDEX #1, saying INTERCEPT MBOX.
This is often 0 (zero) or 9 (nine).
I often correct this value to a non-existing extension number.
Do this:
.M INFO
MOD:255 (often this value)
INDEX:1
INTERCEPT MBOX
MOD: enter here anon-existing extension number.
.E for exit
